George Orwell is primarily a political writer and his essays proves his prowess in that field of writing. For a person who isn't well-versed in this particular subject may think that these collection of essays are too dry and boring. However, the subject is PART of his essay much like his fantastic prose are another PART of his essay. Reading his work just to get a flavor of his writing style is enough to allow you to enjoy his collection of essays on writing, politics, and neo-politics.
If you're a writer and would want to learn from the best then reading this will definitely be insightful. But if you're looking at this book to read Orwell then I'd ask you to steer away from this and instead read his novels: Animal Farm and 1984.
